Hi and thank you!
I created the images with Fusion360 and Inkscape, actually!
For what I know Blender is a powerful tool but not for parametric modeling.
If you want to have a look at the softwares mainly used in the industry, I suggest you Autodesk Fusion360 and Inventor or Solidworks (even if there are more).
Thank you for your comment and appreciation. Good afternoon!
No problemo, and thnks for the data...Gday for u
